If being free from compulsive gambling were in the victims hands, a good number of them would walk out of it immediately. But since the players can't control decisions anymore, they'll need help to be safe. Only few addicts took the problem solo and solved it, but a lot more of them who wouldn't do same, are not to be blamed.
Unfortunately, i believe that becoming obsessed with something is a deeper problem than what we see on the surface.
If you don't get an addiction from gambling you'll get it from drugs or alcohol
It's not the game that makes you addicted, or the smoking or anything else, it's psychological problems that you haven't resolved and therefore it's easier to fall into.
This is according to my modest experience.
